Antioxidant Activity of Phenolic Acids and Their Metabolites: Synthesis and Antioxidant Properties of the Sulfate Derivatives of Ferulic and Caffeic Acids and of the Acyl Glucuronide of Ferulic Acid [PDF]
Journal of Agricultural and Food Chemistry, 2012 The main metabolites of caffeic and ferulic acids (ferulic acid-4'-O-sulfate, caffeic acid-4'-O-sulfate, and caffeic acid-3'-O-sulfate), the most representative phenolic acids in fruits and vegetables, and the acyl glucuronide of ferulic acid were ...

Spectrophotometric Characterization of the Action of Tyrosinase on p-Coumaric and Caffeic Acids: Characteristics of o-Caffeoquinone [PDF]
Journal of Agricultural and Food Chemistry, 2017 New methods are proposed to determine the activity of tyrosinase on caffeic and p-coumaric acids. Because o-quinone from caffeic acid is unstable in its presence, it has been characterized through spectrophotometric measurements of the disappearance of ...

Chlorogenic acid (CGA) and caffeic acid (CA) are two major phenolic acids in coffee. Though the International Agency for Research on Cancer has classified CA as a Group2B carcinogen, coffee consumption seems generally safe within the usual levels of intake and is more likely to benefit health than to harm it. We thus speculated that CGA may effectively

Reduction of Cr(VI) by caffeic acid
Chemosphere, 2007In the soil-plant system, the Cr(VI) toxicity can be moderated through redox reactions involving phenolic substances. In such a context, we report the reducing activity of caffeic acid (CAF) towards Cr(VI) in aqueous phase. The redox reaction between Cr(VI) and CAF was studied as a function of both time and pH at different initial metal concentrations.

Starch digestibility can be decreased by phenolic acids. The physicochemical and digestive properties of high-amylose maize starch, normal maize starch (NMS) and waxy maize starch (WMS) complexed with caffeic acid (CA) were investigated to determine the effects of CA and amylose on starch digestibility.

Growth-promoting Activity of Caffeic Acid
Nature, 1962Vendrig and Buffel have recently stated1 that trans-caffeic acid “may be a very important natural growth regulator, not less important than indole-3-acetic acid”. This conclusion was based on the identification of caffeic acid as one of the active growth substances in an ether extract of leaves, and on growth tests with commercial caffeic acid on 2-mm.

Caffeic acid and rosmarinic acid contents in genus Perilla
Journal of Natural Medicines, 2020Caffeic acid and rosmarinic acid are common components of Labiatae plants, such as shiso (Perilla frutescens Britton var. crispa W. Deane) and Boraginaceae plants. These compounds have various pharmacological activities, such as anti-inflammatory, anti-anxiety, and anti-depressive activities, but the content of these compounds in perilla has not been ...

Neuropharmacological Analysis of Caffeic Acid in Rats
Basic & Clinical Pharmacology & Toxicology, 2006Abstract: The aim of the present study was to investigate the effect of intraperitoneal administration of caffeic acid (0.5, 1, 2, 4 or 8 mg/kg) on elevated plus‐maze and open field tasks in rats and its possible neuroprotection/neurotoxicity using the comet assay.

A simple, sensitive, and accurate liquid chromatographic method with electrochemical detection (ECD) has been developed for analysis of caffeic acid and caffeic acid phenyl ester in propolis. ECD is more sensitive than diode-array detection for analysis of the two phenolic compounds.
